许多特有植物物种属于分类学上复杂的类群。这些地方病经常出现的结果，最近和快速的进化趋异促进过程，如杂交，多倍体和/或育种系统的过渡。在分类学上复杂的群体中，迅速和动态的分化性质导致在执行传统的以物种为基础的方法来保护它们所包含的生物多样性方面出现问题。首先，有关的分类群可能难以界定和确定，导致在实施保护措施方面存在实际困难。其次，基于物种的方法往往无法捕捉到分类学上复杂的群体中多样性的复杂性。为了应对这些挑战，我们制定了基于过程的物种行动计划方法。这是为了保护导致生物多样性产生的过程，而不是专注于保护个别命名的分类群。我们说明的方法，使用一组特有树种（花楸属）的苏格兰阿兰岛，起源于通过结合最近的多个杂交事件和无融合生殖。该计划的重点是优化栖息地管理，以确保花楸在这些进化过程运作的区域内的繁殖和再生，并促进杂交，以确保这一群体的多样性继续产生。(C)2011年，伦敦林奈学会，林奈学会植物学杂志，2012年，168，194203。
Many endemic plant species belong to taxonomically complex groups. These endemics have often arisen as a consequence of recent and rapid evolutionary divergence facilitated by processes such as hybridization, polyploidy and/or breeding system transitions. The rapid and dynamic nature of divergence in taxonomically complex groups leads to problems in the implementation of traditional species-based approaches for the conservation of the biodiversity that they contain. Firstly, the taxa of interest can be difficult to define and identify, leading to practical difficulties in implementing conservation measures. Secondly, a species-based approach often fails to capture the complexity of diversity present in the taxonomically complex group. To accommodate these challenges, we have developed a Process-Based Species Action Plan approach. This is designed to conserve the processes leading to the generation of biodiversity, rather than focusing on the preservation of individual named taxa. We illustrate the approach using a group of endemic tree species (Sorbus) on the Scottish island of Arran that have originated via a combination of multiple recent hybridization events and apomixis. The plan focuses on the optimization of habitat management to ensure the reproduction and regeneration of Sorbus in the zone in which these evolutionary processes operate, and to facilitate hybridization that will ensure the continued generation of diversity in this group.
